CMake Version requirements
|
|
--------------------------
|
|
|
|
To enable use of the emscripten emsdk hack for pseudo shared library support
|
|
without polluting options for consumers we need to use the
|
|
CMAKE_PROJECT_<PROJECT-NAME>_INCLUDE which was introduced in version 3.17
|
|
|
|
For more information check cmake/emsdkHack.cmake

SCons Compatibility
|
|
-------------------
|
|
|
|
There is an understandable conflict between build systems as they define
|
|
similar concepts in different ways. When there isn't a 1:1 relationship,
|
|
compromises need to be made to resolve those differences.
|
|
|
|
As we are attempting to maintain feature parity, and ease of maintenance, these
|
|
CMake scripts are built to resemble the SCons build system wherever possible.
|
|
Where they are not, we will attempt to document common difference in
|
|
the docs (https://docs.godotengine.org/en/latest/tutorials/scripting/cpp/build_system/cmake.html)
|
|
and platform specific differences in their respective
|
|
cmake/<platform>.cmake file.
|
|
|
|
The file structure and file content are made to match, if not in content then
|
|
in spirit. The closer the two build systems look the easier they will be to
|
|
maintain.
|
|
|
|
Where the SCons additional scripts in the tools directory, The CMake scripts
|
|
are in the cmake directory.
|
|
|
|
For example; the tools/godotcpp.py is matched by the cmake/godotcpp.cmake file
|
|
|
|
.. highlight:: python
|
|
|
|
cpp_tool = Tool("godotcpp", toolpath=["tools"])
|
|
cpp_tool.options(opts, env)
|
|
|
|
The CMake equivalent is below.
